EN5311QI

The EN5311QI is a 1A PowerSoC Synchronous Buck Regulator with integrated inductor. The ultra-low-profile regulator is targeted to applications where board area and profile are critical. It is a complete power conversion solution requiring only two low cost ceramic MLCC caps. Inductor, MOSFETS, PWM and compensation are integrated into a tiny 5mm x 4mm x 1.1mm. Engineered to simplify design and to minimize layout constraints. 4MHz switching frequency and internal type III compensation provides superior transient response. With a 1.1mm profile, the EN5311QI is ideal for space and height constrained applications. A 3-pin VID output voltage selector provides seven pre-programmed output voltages along with an option for external resistor divider. Output voltage can be programmed on-the-fly to provide fast, dynamic voltage scaling.
